Moderate

A

No change
B

It will rise
C

It will fall
D

It may rise or fall depending on the density of block

Solution

In both the situation, as the mass of floating block remains same, hence, according to principle of flotation mass or volume of water displaced also remains same. Hence water level will remain same iin both the cases.
